The K&F Concept 72mm Circular Polarizer & UV Protection Filter Kit is a fantastic addition to my photography gear. As someone who frequently shoots outdoors, this 2-piece filter set has elevated the quality of my shots while protecting my lenses.Performance:The UV protection filter is crystal clear and provides excellent protection for my camera lens without affecting image quality. The circular polarizer (CPL) is the real highlight—it reduces reflections, enhances colors, and makes skies look beautifully vibrant. Whether I’m capturing landscapes or water scenes, this filter makes a noticeable difference.Build Quality:The Nano-X multi-layer coating is impressive. It resists fingerprints, water, and scratches, keeping the filters clean and durable even in challenging conditions. The ultra-slim design prevents vignetting, which is a huge plus when shooting with wide-angle lenses.Ease of Use:The included up & down lens caps are a nice touch and make switching filters on the go quick and easy. The filters thread smoothly onto my 72mm lens, and the snug fit ensures there’s no wobble or misalignment.Pros:• High-quality glass with 28 multi-layer coatings for HD clarity• Excellent polarizing effect and UV protection• Slim, lightweight design prevents vignetting• Durable and easy to clean with Nano-X coating• Convenient lens caps for storage and quick accessCons:• None so far—it delivers exactly as promised!For the price, this kit offers exceptional quality and value. It’s perfect for photographers who want reliable, professional-grade filters without breaking the bank. Highly recommended!

My favorite filters, and at this point K&F is my go to brand. The front and rear caps are nice.They're all aluminum and heavy enough that they'll last.

The first thing I did when I received the set, was to take hi-quality photos of a print test page and then zoom into compare. I could not see a visible difference. Now, it's not scientific; just a home test, but I couldn't tell the difference. I used the UV filter on a trip to Africa, it was very dusty. When I noticed dust on the lens, I just blew it off. I only had to cleanse the lens a couple times (e.g. from waterfall spray). I use this on Sony RX10 MKIII. I highly recommend this UV filter.I tested the Circular Polarizing Filter, and I was a little hesitant to tighten it because of the review/complaints about not being able to remove it; it is very skinny and I could see how it would be difficult to grip- so, I only had one opportunity at a slow moving creek to test the polarizing effect, I didn't see the benefit but I don't believe I gave it a fair test. IMO, I do not have enough use to give a reasonable review.

This lens kit works great for the price that came with 2 good metal caps which are convenient on the go. The UV filter can protect the lens while the CP filter can block some lighting out; however, it can't block lighting as well as the K&F True Color Ultra-Low Reflectivity [highlight in teal color] .

First of all, the quality of the lens kit is very good. As a less experienced photographer, it's not quite what I was hoping for. I had (mis) understood that the lens cap would be magnetic. (I gathered that from reviews, though the company never made that claim.) Instead, the lens cap screws on, which is awkward because the polarizing lens also rotates, making the process a bit difficult, especially when wearing gloves.

Fit and finish excellent!! Comes with a tiny draw string pouch and fits my lens perfectly. I highly recommend this filter set for anyone with a high quality lens for ANY camera.

I have these for all of my lenses. The magnetic features are the main reason I chose this line. They are swapped out much more quickly. The magnetic lens cap is awesome on its own and I have never lost one...unlike the pinch type which can be knocked off if not perfectly placed. Other high quality filters are very good but usually priced much higher and are not magnetic.

I bout this item back in 2023 to go on my Sony kit lens. This lens filter held up great on 3 US Navy cruises (used it for photos during port calls and on the flight deck). However I unpacked my camera from deployment and found the circular polarizer filter had come loose in the housing and set rings were dislodged. Not sure how this happened as the camera was in a protective bag the entire time during transport. Either way, I reached out to K&F directly with photos of the issue and they sent me a replacement filter. Overall it was a great experience with their customer service.

Ok

Great quality, well made, good value.

I have other K+F filters for other lenses and they have been exceptional. I ordered this duo for the Sigma APS-C 18-50mm F2.8 zoom which I use on my Sony A6000. If I stack both filters together I get strong black corners. If I zoom from 18mm to 19.5mm they are gone. If I use one filter at a time no problem. So I have decided to leave the polarizer on for the summer and re-install the UV in the fall. Unless I plan to shoot 20-50mm on a particular day. These filter rims are so thin I dont believe there is anything in the marketplace that could improve this situation. I have stacked K+F on other lenses with no issues. Must just be this Sigma lens design.

Bought this despite very less information on dpreview or any other such website, and while I am not disappointed there are certain things I don't like about this such as the cap. The cap is screw on and this means stock cap of lens cannot fit and secondly cannot layer in filters. Tried to layer on top of this the ND filter and it didn't work.
